I am not to familiar with Neutral Regulator. Some water conditioners contain buffers because they will lower pH in soft water. Amquel plus has this. I am also assuming you have checked the tap water after it has "aged". Some water has trapped CO2 in it. When the CO2 disapates, the pH will rise. CO2 is a carbonic acid, so it is acidic and will lower pH. Try to test your tap water after it has aged a day or to in a container. You could also take a container of tap water and add an extra airstone or bubbler if you have one to speed it up. Put the airstone in the container at the highest setting available to really bubble the water and aerate it. This drives off the CO2 quickly, like an hour or 2 to be sure. Then test to see if there is a difference.

Other factors that will increase pH-
1)gravel - even though some gravel is labeled "wont affect pH" it does. Take a handful of gravel and put it in a bowl. Pour some white vinegar in the bowl covering the gravel by an 1". Wait 10-15 minutes. Look at the vinegar over the gravel and see if the gravel is sending any bubbles to the surface. It will usually be a steady stream of tiny bubbles. No bubbles assume gravel is inert to pH.

2)Decorations- ceramic painted decorations can leech into the water and raise pH. Also, SEASHELLS will definately buffer pH. They are pure calcium carbonate. ROCKS- test them the same way as the gravel test. Most "RIVERSTONES" will buffer pH unless sealed in epoxy. Marble, limestone will buffer pH.

Most likely it is the Neutral regulator you have if there is nothing else you are adding or it is not the things I mentioned. If your tap water pH is 7.0, you really don't need a neutral regulator, it is already neutral. Try Seachems Prime instead for dechlorination and other conditioning.

There's also an outside possibility that your test kit is faulty. Do you have a backup?

No,but I am ordering a new one. Should be here in a couple days, thanks for the suggestions. Also, am going to start using the Prime product. This is such a good forum, you all always have good ideas and I appreciate being able to draw from other's experiences. Thanks again.

Before you add fish do a water change without adding any chemicals. The clorine disappates from the water within 24 hours anyway. I never use clorine remover.
